The power supply requirements are pretty straight forward.

If you look at the TBW-5 setup on my web page,  you'll see the transmitter is enclosed in the rollable power supply.    I liked the idea of a rollable power supply.

Instead of building a new PS for the TBW-4 setup, I decided to build a general rollable power supply that I could use for multiple radios -- just roll it over to whatever radio I decided to use.

The existing supply had safety issues (such as the old 2KV rectifiers near the exposed rear opening, and just heavy wire for the 2KV circuit).   Also,  the PS used welded angle iron.  It was nicely built, but there was no way to access the lower deck for maintenance.    So, I gutted the rollable cabinet and rebuilt/upgraded the power supplies within it.

I used the existing 2500V transformer and used K2AW diode blocks as well as actual HV wiring.   I also used a different transformer for the 500V supply that will give me 800V or so for other projects.    All variac controlled and all have full voltage and current metering -- using shunts etc so there is no HV or current going to the front panel meters.

I've attached a photo that was an "in progress" photo from a few months ago.  As of the current date, the 2500V ahd 500V supplies are finished and working.   They could be used to power the TBW-5 or TBW-4 transmitters.

I was going to put the 3 filament transformers in the same rack,  but decided to mount them in the Rectifier Modulator Unit as the two 800 Hz transformers are missing and that opens up some space.

One of my "design criteria" was to only use parts that were on "the pile", even if smaller / lighter solutions were available.
